I had a major problem with the report wizard in the Excel add-in of Thomson One Banker: a curline error made it impossible to download data for a specific list of companies.
I think the reason of the error is somehow in that particular list of companies, because the error appeared in Excel 2003 and 2007 and on multiple computers. This is the solution I came up with: I downloaded the list from the server, used the PFDL-function to request the Worldscope name and WorldscopeID (WS.EntityName and WS.WorldscopeID). Then I deleted the companies without a name and ID and uploaded the new list to the server of Thomson. That cleaned list gave no problems.
